Question

Which of the following statements is/are true? Check all that apply. A conservative force permits a two-way conversion between kinetic and potential energies The work done by a conservative force depends on the path taken. A potential energy function can be specified for a conservative force. The work done by a nonconservative force depends on the path taken. A potential energy function can be specified for a nonconservative force A nonconservative force permits a two-way conversion between kinetic and potential energies. Submit My Answers Give Up

Explanation / Answer

1) True. Conservative force permits the conversion between kinetic and potential energy. Eg: Gravitational force.

2) False. Work done by a conservative force is independent of the path taken. Work done by gravity.

3) True A potential energy function can be specified only for a conservative force. Eg: Electrostatic potential and electrostatic force.

4) True. Work done by a non conservative force is path dependent. Eg: friction force.

5) False. A potential energy function cannot be specified for a non conservative force.

6) False. Non conservative force does permit a two way conversion between kinetic and potential energies since some energy is lost.
